Volume Two of this new documentary history of the Soviet Union comprises over 270 documents and is organised into four chronologically distinct parts, subdivided thematically; it runs from the fraught diplomatic and military preamble of the Great Patriotic War to the final fracturing of the USSR along the national fault-lines of its 15 Union Republics. Slight overlap of chronological coverage with Volume One allows increased attention in Volume Two to foreign affairs. Areas in this volume that attract greatest student interest are the epic dramas at the beginning and end of the period -- the Great Patriotic War and Perestroika. The commentary is by Edward Acton, Professor of Modern European History at the University of East Anglia, who has published widely on the Russian revolution and the history of Russia and the USSR. The documents have been translated by Tom Stableford, Assistant Librarian, Slavonic and East European Collections, Bodleian Library, Oxford.
